itsourcecode Electronic Judging System SQL Injection Vulnerability in Login.php

A SQL injection vulnerability has been identified in the Electronic Judging System version 1.0. The issue resides in the login.php file within the intrams/admin directory. This vulnerability allows remote attackers to inject malicious SQL queries through the username parameter, exploiting inadequate input validation. The exploitation could lead to unauthorized database access, data manipulation, and potential disruption of services.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to the login.php file with a crafted payload that exploits the SQL injection flaw. The payload should include a SQL injection string that manipulates the SQL query processing, such as using time-based blind SQL injection techniques.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall system security.
